The End Of Dengue Fever? Mosquito Trials Shows Compelling Results!

Dengue is commonly known as “break-bone fever” because it causes severe pain in muscles and bones. An eruptive outbreak can even overwhelm hospitals. The World Mosquito Program representative said that the result of a three-year randomized controlled trial provided “compelling gold standard evidence” of the efficacy of the Wolbachia method in controlling dengue.

The result of the study was groundbreaking. Dengue fever cases have been cut by 77% that manipulates mosquitoes that spread, and there was an 86% reduction in people needing hospital care when the insects were released, scientists said. The development boosts hope of eradicating the virus that infects 390 million people around the world each year. Scientists infected the mosquitoes with a “miraculous” bacteria called “Wolbachia”. These bacteria cut the insect’s ability to spread the infection. 

 According to the World Mosquito Program, nearly 141 countries are affected by dengue fever. Still, the most significant dengue epidemics in recent years have occurred in Southeast Asia, America, and the Western Pacific. Over 40 percent of the world’s population is at risk of getting infected. Each year, the disease causes around 25,000 deaths worldwide.

The trial was carried out in Indonesia’s Yogyakarta city. It is an urban area home to about 300,000 people. The 26-square-kilometer area of Yogyakarta was divided into 24 clusters. In 12 of those clusters, the team set out containers of Wolbachia-carrying mosquito eggs every two weeks for 18 to 28 weeks. In due course, the microbe spread through the local mosquito population: Ten months after releases started, the prevalence of Wolbachia among mosquitoes in the treated clusters had climbed to 80% or higher. The technique has been so successful that the mosquitoes have been released across the whole city. The project is moving to surround areas to eradicate dengue in the region.
